IMPROVEMENT lN LOOM'SHUTTLES.

Specification forming part 01 Letters Patent No. 188,926, dated March27, 1877 application filed September 2, 1876.

To all whom it may concern Be it known that I, EZRA W. MARBLE, ofWilkinsonville, county of Worcester, and State of Massachusetts, haveinvented a new and useful Improvement in a Weavers Shuttle forCotton-Looms, of which the following is a specification:

In the accompanying drawing, Figure 1 is a side View of my improvedshuttle, partly in section to show the construction. Fig. 2 is a topview of the same, and Fig. 3 is a detail view of the spindle. section ofthe shuttle.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved shuttle whichshall be so constructed that the cop may be placed upon the spindlewithout having its interior snarled, as is the case when the ordinaryspindle is used, and thus avoidthe great waste of cotton from saidsnarling.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

In the drawing, A represents the body of the shuttle. B is the spindle,which is made of two pieces of steel, welded together at the point. Uponthe other end of the spindle B is formed the head, which is perforatedtransversely, to receive the pin by which the said spindle is pivoted tothe shuttle A. The inner sides of the parts of the head are beveled ofi'from the center of the pivot-hole to the end of said heads, as shown inFig. 3, so that when said ends are left free, the two parts of thespindle may be close together, to enable the cop to be easily slippedupon the said spindle without having its interior snarled, and so thatwhen the ends of the parts of the head are pressed together, the middlepart of the parts of the spindle will be made to bulge, as shown in Fig.2, so as to fasten the cop securely upon said spindle.

C is a grooved socket, which is secured in Fig. 4 is a horizontal theend of the shuttle A, in such a position that when the spindle B israised into position to receive the cop, as shown in Fig. 1, the head ofthe said spindle will pass out of the lower end of the groove of thesocket C, so that the cop can be readily slipped upon it; and when thespindle B is lowered into position for use, the ends of the parts of thehead will enter the groove of the said socket U and be pressed together,causing the middle part of the spindle to bulge and hold the copsecurely.

The spindle B is held in place, when lowered into position for use, byalever, D, which is pivoted to the shuttle A at its middle part, withone end resting against the end of a coiled spring, E, the elasticity ofwhich holds its other end pressed against the head of the spindle B, asshown in Fig. 1.

I am aware that it is not new to use a lever in shuttles; but I hold thespindle in place by a lever that supports the heel of spindle with anoval end, while it is itself supported at the other end by a spiralspring. The oval end of lever is designed to help in closing up thespindle when raised at the point out of the shuttle-box to receive thecop. I am also aware that sockets for the end of spindle are not new;but my socket is made to fit a round hole with a side groove at thebottom, to accommodate each of its cars. It is inserted within theshuttle by placing the ears lengthwise ot' the slot that is intended toreceive the spindle, and, aft-er being pressed down to bottom of hole,turned around to let the ears into the side groove; hence What I claimas new is The combination of a socket, 0, having the described grooveand ears, with a shuttle having a spindle-slot, round hole, and bottomside groove, as and for the purpose specified.
